SLUG-MOLD.

To all whom it may concern:

Be it known that I, JOHN KEENAN, a. citizen of the United States, and a resident of Chicago, county of Cook. and State of lilinois, have invented certain neu and useful Improvements in Slug-Molds. of which the following is a specification.

My invention relates to improvements in printers line casting machines, and has particular reference to improvements in line or slug casting molds for use upon such niachines.

The object of my invention is to facilitate. and ehe-apen the production of printing slugs, particularly that form of slug known as a skeleton slug, and to simplify and re duce the cost of the necessary parts f r making skeleton slugs ot different lengths.

A further. object of my invention is to provide a mold by means of which skeleton slugs of difi'erent lengths can be produced Without the necessity of using liners of special cross section. in other words. my object is to provide a slug mold by means of which slugs having thin portions in the bodies and wide tacos can be cast ot' any desired length Within the capacity of the mold by the use of the usual parallel thickness liners.

*ly invention resides in a mold for line or slug casting machines. one side of which is provided with a series of spaced recesses, openings or notches which open into the body ot the mold and through the front face thereof, the intermediate portions of the mold being left intact \vhercby ordinary parallel thickness liners or liners unprovided \vith groove filling flanges can be used in conjunction therewith to produce slugs of ditl'erent lengths.

My invention ale' o consists in the various arrangements and associations of parts and in the peculiar features 01" construction. by means of which the above mentioned and ther objects are attained. and all as herein described and particularly pointed out in the appended claims.

This present application is a continuation of my early application. Serial No. (392439, filed April 1912. and entitled Slug molds" in so far as it relates to the subject matter thereof.

l\1l v invention will be more readily understood by reference to the accompanying drawings, in which:

It has be which would be equally ing skeleton slugs and v the necessit s1 ve liners,

en my object to provide a mold etlicient in producich would obviate y of this complement of expenrestricting the liners to what are known as the standard or parallel thickness liners and by means of these standard liners being able to produce skeleton slugs of the \arious lengths desired.

. My improved mold has the general appea "ance and is biiilt up of the parts usually employed in a line casting mold employed upon linotype and similar line casting machines. It consists of a base member 2, and a cap member 3, separated from each other by a space 4 and held in position one upon the other by any suitable means, such as screws 5. The cap is held in its spaced relation from the base by means of a permanent liner or spacer 6 at one end, and a changeable liner or spacer 7 at the other end. These spacers or liners are clamped between the adjacent opposite faces of the base and cap, and are held in position by the clamping of the cap upon the base and are adapted to space the two parts of the mold apart a suflicient distance to provide a slug space 4 in which the thin portion of the slug body can be formed. So in r the description would apply to any standard line -asting mold, and a'mold which would produce a solid parallel thickness slug. the face of which isot sub' stantially even width with the solid body of the slug. There are now being used matrix characters termed head letter characters which have required the formation of slugs with widc faces and to accommodate these high characters, skeleton slugs have been produced to reduce the amount of metal which it is necessary to use for the production of these wide-faced slugs. These skeleton slugs have faces wide enough to accommodatc. the highest characters associated therewith. but thc. body of the. slug has a relatively thin portion. The slug is also provided with intcgral spacing bars cast with the body of thy slug and adapting the slugs whcn asscmldcd togctller to securely support each other in proper rclatirc position. .\s suggested above, the formation of thcsc slugs has heretofore required the equipment of the machine with a great lincrs of special cross section and by means oi my improrcmcnt l have been able to eliminate this ncccssity ot' spccial liners and reduce the liner equipment of each machine to a minimum quantity of ordinary parnllcl thickness liners. For the purpose of producing a wide face. to form a base. upon which to cast or support lhc rclatircly high printing charm'tcrs, I provide in one mcmbcr ol' the mold. preferably in the cap. a serics ol' rcccsscs, openings or notchcs 8 which t'rcclyopcn into the slug space i adjacent to tho'i'ront 'l'a cc of thc mold and also through the .l'rout l'acc. oi" the mold. l prcl'cr to spacc lhcsc rcccsscs or opcnings at rcgular inlcrrals along the facc of thc mold and llugrarc :ldaplcd to proridc a scrics of no wardli cxlcnding projections on one side quantity of of the slug. The forward or frontfaces 10 of these projections lie in a. plane with the blank face of the slug which is adapted to be cast in the mold, and the faces 10 with the adjacent face of the slug itself form a. relatively wide platform or base adapted to rcceive and support the printing characters. 'lhese characters are adapted to be formed by the aid of matrices it which are provided with recesses of a form to produce the character desired. These matrices 11 are. arranged in positions along the face. of the mold as indicated in Fig. 2, and in conjunction with the space i and the recesses 8 form a space which is adapted to be iillcd by molten metal and thereby form a line or slug. *lach matrix carries in its edge. which is presented to the mold, a dcprcssion 12 which serves to form a. letter base, as indicatcd at 13 (l igs. 10 and i3) and a character recess it which is formed in the body of the metal of the matrix and opens into the base recess 1;. This character recess is adaptcd to form a printing face 15 upon the base 12%, as clearly shown in Figs. ltl'aud ii"). The base iii of the various letters is of a width to correspond with the bright ot' the. letter which it is intended to carry, and conscqucntlv for low letters or periods this base is r latircly of small dimensions while for the tallest lcltcrs, which the slug is dosigucd to carry, this base cxtcnds from one edge to the other of the sing. The spaces bctwccn the projections l'ormcd on the slug, are not therefore usually mnnpletcly covered by the bases of the printing type. This, however, dcpcnds on the rclatirc size of the bases and the slug upon which they are cast. The slugs illustrated in Figs. 5) and l4 are what are termed blank slugs, that is, slugs unprovided with printing characters and these would be produced it a line composed of blank matrices as distinguished from lctlcr matrices wcrc used in the casting operation. in ordcr that the slugs cast in the mold may be arranged in a column. and whcn thus arranged may be sccurcly clampcd together in proper rclatirc position. i proride groovcs it) in the cap of thc mold which extend from thc front face. to thc rcar facc thereof, and the upper edges of which arc substantially parallcl with the body of the mold. This formation or construction of the cap forms the slugs with spacing ribs l'i' which serve to hold the slugs in propcr rclalirc. position \vhcn they are sci in a form. These slots lli t'orm continualions ol' certain of the. spaces i and the uppcr cdgc ol' the slots are substantially in the plane. ol the upper ends of lhe rcccsscs H. 'lhc rcccsscs 8 and lhc slots H' are both tapcrcd from their oulcr cdgcs toward the body of the slug, so thai lbc parts cast thcrcin will rcadily l'rcc lhcmsclrcs from the mold, whcn it is dcsircd to cjcct the slug from the mold.

Slugs usually vary in length by certain definite amounts eon'nnonly in pica lengths, and I preferably form the recesses or openings 8 of such a size and spacing that the partitions 18 which separate these notches are spaced apart substantially equal with the variation in the. lengths of slugs or lines desired to he produced by the mold. These partitions 18 are relatively thin and their tree edges 19 and 20 are respectively llush with the lower face or bottom of the cap and with the front face thereof. Should it he desirahle to make a slug of less length than the full length of the mold I insert a liner 7 at one end of the mold, which is of such a length that its inner end is spaced from the inner end of the opposite liner a sullicient distance to make a slug of the desired length. and I arrange the partitions 18 in such a manner in relation to the ends of the liners and the length of slug which it is desired to make that the inner end of the liner T is immediately helow and in contact with one of the partitions 18. consequently when the molten metal is forced into the mold space from the rear in the usual manner and the matrices are loc-kcd in position in front of the mold the metal is prevented from'flowing longitudinally along the face of the mold for it is completely stopped or dammed hy the inner end of the liner 7 and the ('oiipt'l'utillg partition 18. To make slugs of dillcrcnt lengths. it is'only necessary therefore to provide liners of the form shown in Fig. l. that is. simple parallel thickness liners. aml ol the various lengths desired. It is ohvious that if it is desired to design a machine to produce slugs vary ingh other than pica measures, that is, say varying hy one-hall pica measures it would only he necessary to properly space or position the partitions 18 and provide liners T of suitahlc cooperating lengths.

It will now he clear that the series of recesses 5 form what may he termed a longitudinal groove. along the front edge ol the cap, divided into a plurality of small sec tions h v the partitions l8 and that to all intents and purposes the product ol the mold may he descrihcd as hcing a linotype slug having a thin hody portion and a wide l tlf.

.\s many modifications of my invention will readily suggest themselves to one skilled in tl art. I do not limit or conlinc, my invention to the spccilic structure herein shown and dcscrihed.
